WebTo promote the use of small hydropower generation it is required to reduce costs and increase efficiency. Unshrouded runners are proposed to simplify the manufacturing process and also to reduce the manufacturing costs. In this paper, the computation results of optimized unshrouded runners are presented. Web1 Mar 2024 · Alas, to realize such potential gain, one must effectively couple the turbine with the detonation combustor, whose exhaust conditions differ substantially from current state of the art gas turbines.

WebThe conclusions were obtained by analyzing the flow conditions which involved Re, vorticity, and rothalpy in the flow passage and viscous dissipation. When the viscous dissipation generated heat in the passage, temperature was increased and viscosity was decreased, thus accelerating the development of turbulence.
